Overall it's a different market, bigger than the difference between handeld and homeconsoles.
Some game genres have a record of doing less than average on PC (Fighting for example), other genres are typically associated with PC (strategy and simulation subgenres, mostly).
The economy is different, with now a huge lead for free to play games while subscription based ruled before. Of course, the typical 60$ game is still doing good.
So it's hard, and IMO useless, to search for a universal ratio between console and pc sales. And Titanfall pc sales are probably 75% digital anyway. (and people are waiting for a crack)
